What geoffkait said may sound funny because he is that way some of the time. But that is a real possible solution. I have used that method and it helps out a noticeable amount. Geoff probably knows why, but it has worked for me. If you do it, get some that are cotton or wool, preferable wool and get a neat design, It can look good on there with a neat design. Geoff is not only funny 1/10 of the time but he is practical about 1/10th of the time.
